Abstract

Incinerator dryer grates with temperature control provided by two phase steam. Very wet bulk refuse entering an incinerator sits on a grate before falling on a hearth floor below. This drives off volatile hydrocarbons and allows drying. The grate may also provide combustion air. The drying process causes the moisture content of the refuse to fall below 50 percent where combustion may occur. Two phase steam passes through separate channels in the grate to control its temperature. The oxygen containing gas emanating from the grate onto the combustion chamber may contain gaseous products of combustion, or flue gas, with or without air to make use of the former's heat and moisture content. When the flue gas contains chlorine, its temperature should, through the addition of cool air, fall within the range of 400 degrees to 750 degrees F.
